MODIFIED CEMENT TILE ADHESIVE AND GROUT

Methods of formulating, premixed cement-based tiling compositions and application of such premixed cement-based tiling compositions as an adhesive or grout. The premixed cement-based tiling compositions include a premixed cementitious formulation having a pH and an alkali activation constituent. The premixed cementitious formulation includes an aluminous or a calcium aluminate cement slurry in an amount of about 35 wt. % to 50 wt. % in combination with one or more filler or modifier materials present in an amount of about 40 wt. % to 65 wt. %. The alkali activation constituent destabilizes the premixed cementitious formulation by increasing the pH thereof to generate a reaction between the premixed cementitious formulation and the alkali activation constituent resulting in the cement-based tiling composition for use as an adhesive or a grout. The alkali composition may be sodium hydroxide supersaturated with lithium carbonate.
